The heat can make your usual workout a lot more difficult. It also puts you at risk of heatstroke if you’re not careful. If you want to get your sweat on when it’s burning up outside, adjusting your intervals can make it a little easier and safer.

The hotter it is, the slower you run—but humidity plays a role too. When the air is full of moisture, sweating doesn’t cool you down like it usually would. You won’t be able to run as fast, because your body is trying to prevent you from overheating.

You’re not going to like this, but your air-conditioner is actually making it harder for your body to handle the heat outside. If you want to feel more comfortable outdoors during the hot summer months, you need to cut back on your AC use.

People who are overweight seem to sweat more than svelte athletes—but that’s not entirely because of body fat. A new study explains why losing weight might not affect your sweat rate the way you’d think.

The scorching summer heat is hard on our bodies, our moods, and our electric bills. Don’t let the temperature get you down, though. These ten tips will help you keep cool even if it feels like the sun is out to get you.

Getting a good night’s sleep on a hot day is no easy task, especially without air conditioning, but there are plenty of things you can do to beat the heat. This graphic from the folks at the Sleep Matters Club is packed with tips—some of which we’ve mentioned before—to cool off and get some rest.

Nobody likes to feel sluggish and sweaty, so when the sun is set to “broil” we understand that you’d rather take your workout to an air-conditioned gym. But if you tough it out in the heat, not only will the workouts get easier, you’ll also have better endurance when the mercury drops again.
